The US dollar has faced downward pressure in recent weeks following President Donald Trump’s public criticism of Federal Reserve Chair Jerome Powell and the central bank’s rate-hiking stance. This political skirmish has reignited debates about central bank independence and its impact on currency markets. Meanwhile, Latin American currencies—including the Mexican peso (MXN), Brazilian real (BRL), and Colombian peso (COP)—have seen notable appreciation against the dollar. This article explores the dynamics at play and evaluates the investment implications for emerging market currencies.

President Trump’s repeated calls for lower interest rates—and his thinly veiled attacks on Fed Chair Powell—have unsettled markets. Historically, such political interference has eroded confidence in the dollar’s stability, as investors question the Fed’s ability to operate independently. This uncertainty has contributed to a 2% decline in the US Dollar Index (DXY) since early August, with the index now hovering near six-month lows.
The weakening dollar has provided a tailwind for Latam currencies, but domestic economic conditions also play a critical role. For example:
1. Mexican Peso (MXN): The
While the near-term outlook for Latam currencies appears positive, several risks could reverse the trend:
- Fed Policy Uncertainty: If the Fed pauses its rate cuts, the dollar could stabilize or rebound, undermining gains in emerging market currencies.
- Commodity Prices: Many Latam economies rely on commodity exports (e.g., oil, copper). A drop in commodity prices could weaken currencies despite dollar weakness.
- Domestic Political Risks: Brazil’s stalled pension reform and Argentina’s debt crisis highlight that macroeconomic stability remains fragile in some regions.
Recent data underscores the divergence in monetary policy between the US and Latam:
- The Fed has cut rates twice in 2019 but may pause further cuts if inflation picks up.
- Brazil’s Selic rate is now at a historic low of 6.5%, with markets pricing in one more cut by year-end.
- Mexico’s central bank has maintained a 8.25% policy rate, balancing inflation control (currently at 3.4%) with growth needs.
Latam currencies present an attractive entry point for investors, but success hinges on a nuanced approach:
1. Focus on Fundamentals: Prioritize countries with strong external balances, low inflation, and credible central banks, such as Colombia and Mexico.
2. Avoid Overexposure to Fiscal Weakness: Avoid Argentina and Venezuela, where political and economic instability overshadow currency movements.
3. Hedge Against Dollar Volatility: Use currency forwards or options to mitigate risks if the dollar rebounds.
The current environment offers a rare confluence of dollar weakness and improving Latam fundamentals. However, with global growth slowing and trade tensions lingering, investors must remain vigilant. For now, the MXN and BRL appear among the most compelling plays, backed by data showing BRL appreciation of 15% year-to-date and MXN gains of 8% in 2019. As always, diversification and risk management will be critical to capitalizing on this emerging trend.
